  • DeFi requires no third party or centralised authority to operate and offers many features of traditional finance, like lending/borrowing and trading.
  • DeFi products utilize smart contracts that define how DeFi products operate and work.
  • DeFi can be used anonymously but DeFi “wallets,” which are automatically assigned a user ‘address’, are needed to hold assets and operate decentralised applications.

What is Decentralised Finance?

Decentralised Finance (DeFi) are financial products on the blockchain that operate without a centralised authority. In DeFi, it’s possible to take a loan, buy coins, go long or short, trade an asset peer to peer, bid on items and more without overhead third parties or centralised authorities. 

DeFi is able to operate without third parties thanks to “smart contracts” that automatically execute orders and demands for users that interact with DeFi products. Smart contracts are able to create stable rules for each DeFi service and how that service should be used.

Unlike traditional finance (TradFi), DeFi operates globally 24/7. Anyone with a DeFi wallet and an internet connection can interact with DeFi products freely. This makes financial services more inclusionary and available to people who would not usually have access to them. 

What’s the difference between DeFi and TradFi?

TradFi refers to the conventional financial world, run by financial institutions and banking associations. When compared to DeFi, TradFi is highly centralised and controlled by financial regulators, banks, and the government.

Unlike DeFi, TradFi does not have transparent order books and most financial information relating to companies and institutions is not made available to the public. In DeFi, anything that occurs is publicly viewable; from small transactions to the code used to create dApps.

There are many actions that are possible in DeFi that are not available using TradFi, such as flash loans, 24/7 trading, accessible low trading fees and more.

What’s the difference between DeFi and CeFi?

CeFi stands for centralised finance. CeFi includes most of the abilities of DeFi but provides variations of extra security and accessibility for users who want less risk involved when using DeFi products.

Being a decentralised network with no authority or regulation means DeFi is prone to malicious activity and programming bugs. CeFi aims to curtail the issues of security and usage difficulty while keeping the core concepts of DeFi available to a wider audience. In CeFi it’s possible to lend and borrow assets, trade crypto coins, and use credit cards with crypto rewards.

Examples of CeFi include websites like Binance, Coinbase and where users must create accounts following know-your-customer (KYC) guidelines to gain access to centralised exchanges, centralised wallets, crypto credit cards, centralised yields and more.

  • Chainlink. Allows external data from the outside world and internal data from the blockchain to be sent and received to various products, individuals, databases and more.
  • Ripple/XRP. A digital payment network, exchange and remittance service that uses its cryptocurrency XRP for payments and as an intermediate currency for other currencies tradable on the network.
